Today, with the rapid development of optoelectronic technology, the performance testing of photodetectors
has become a key link in scientific research and industrial applications. However, the complexity of the packaging
structure, electrode layout and test environment of different types of detectors poses severe challenges to the
compatibility, stability and operational convenience of the fixtures. With over two decades of technological accumulation
in the field of optoelectronics, Beijing Saifan Optoelectronic Instrument Co., Ltd. has launched the DRS020-3.0
photodetector fixture and the 7-SCF08 3M battery fixture. Through innovative design, it addresses the
pain points of the industry and provides efficient solutions for optoelectronic testing.
Precise adaptation, covering diverse testing requirements
The DRS020-3.0 fixture of Saifan Optoelectronics is specially designed for the performance testing of photodetectors.
Its core advantage lies in the compatibility of "one fixture for multiple uses". For detectors with packaging, the fixture
can be adapted to devices with pin diameters within 3mm and spacings ranging from 2.5mm to 25mm. Fixation can be
completed simply by inserting the pins into the gaps of the crimping spring pieces. For unpackaged detectors, the fixture
table surface can support devices with an area of 30mm×30mm or less, and can be quickly fixed through tablet pressing.
This design has completely solved the problem of low testing efficiency caused by size limitations of traditional fixtures,
and is particularly suitable for the research and development scenarios of new photovoltaic materials such as perovskite
cells and heterojunction cells.
The 7-SCF08 3M battery fixture further expands the adaptation range. Its open structure can flexibly adapt to standard
solar cells with an electrode spacing of 2.54mm (1/10 inch) and no more than 6 electrodes. Through modular adjustment,
the fixture can quickly adapt to batteries of different sizes, avoiding test errors caused by fixed parameters. Especially in the
micron-level thickness test of thin-film batteries, its dedicated locking seat can ensure uniform contact pressure and prevent battery damage.
Stable transmission ensures data accuracy
In photoelectric testing, the stability and anti-interference ability of signal transmission directly affect the accuracy of data.
The fixture products of SOFN Instruments have significantly improved the testing accuracy through the four-wire testing
mode and anti-electromagnetic interference design. For example, the 7-SCF08 fixture is equipped with two standard BNC interfaces,
supporting the simultaneous output of current and voltage signals, effectively reducing the influence of contact resistance on the test
results. In quantum efficiency (QE) testing, the four-wire connection can precisely separate the series resistance and parallel resistance
of the battery, improving the resolution of spectral response analysis. In addition, the built-in band switch design of the fixture enables
users to switch the test electrodes with one click without repeatedly disassembling the battery, increasing the testing efficiency of
multi-electrode batteries by more than 50%.
The DRS020-3.0 fixture achieves quick connection and insertion through press-type terminal blocks, which are easy to operate and have
reliable contact. Its electrode wires can replace the terminal blocks, and the other end is connected to the acquisition device according to
the positive and negative poles, further simplifying the testing process.
System integration and the construction of a full-dimensional testing solution
SOFN Instruments is well aware of the systematic requirements for optoelectronic testing. Its fixture products can be seamlessly integrated
with accessories such as the 7-SCF06A/B three-dimensional probe base and the 7-SCF09 sealed 3M battery fixture, forming a comprehensive testing
solution covering all dimensions including spectral response, I-V characteristics, and dark current. For example, by combining the 7-SCF06A three-dimensional
probe base, users can achieve electrical performance analysis with a spatial resolution of micrometer level, which is suitable for defect location and carrier mobility
research of perovskite cells. When paired with the 7-SCF09 closed fixture, it can simulate the stability test of batteries in high-temperature and high-humidity
environments, meeting the verification requirements of outdoor application scenarios for photovoltaic modules.
In addition, the fixture products of SOFN Instruments strictly follow the ISO9001 quality system certification standards, and quality is controlled throughout the
entire process from research and development to production. Its R&D team integrates two core patents, namely spectral testing technology and precise motion control
technology, to ensure the outstanding performance of the fixture in terms of micron-level positioning accuracy and millisecond-level response speed.
Service escort, ensuring a full user experience throughout the process
As a "specialized, refined, distinctive and innovative" small and medium-sized enterprise in Beijing, SOFN Instruments has established a service system covering the
whole country. Through the service hotline 010-80885970 and the wechat official account platform, it provides users with 7× 24-hour technical support. From product selection,
installation and commissioning to later maintenance, our professional team will provide full support throughout the process. For instance, in response to the issue raised by
customers that "the edges of the battery cells are fragile", the engineers of Saifan optimized the elastic contact plate design of the fixture, reducing the battery damage rate to
below 0.1%, and provided a free customized fixture modification plan.
Conclusion: Empowering the future of Optoelectronics with innovative technologies
In the current era of accelerated iteration of photovoltaic technology, the photodetector fixture of SOFN Instruments, with its three core advantages of precise matching,
stable transmission and system integration, has become a key tool for promoting the industrialization of optoelectronic research. In the future, SOFN Instruments will
continue to empower scientific research with innovative technologies and explore the infinite possibilities of green energy and optoelectronic technology together with
global partners.
